What is electricity??

Electricity is moving charged particles


Every atom is made of particles

  • Protons
  • Neutrons
  • Electrons

Electricity is moving charged particles

  • high potential -> low potential
  • Moves energy that can perform work
  • high potential -> low potential,
  • Moves energy that can perform work

Can pretend it’s like water!

How does electricity do stuff?

  • Voltage
  • Current
  • Resistance
